Biohydrogen production by dark fermentation: biomasses potential and microbial variability

Creators

Description

In the context of energy transition, this work deals with the exploration of new potential biomasses for the production of a clean energy vector, hydrogen (H2). During this thesis, a process of H2 production by an endogenous fermentation from winery waste has been developed without any additional energetic consumption. The influence of operating parameters was studied. Finally, the type of biomass has an influence on the H2 production, not only because of initial biochemical composition, but also because of the endogenous microflora which orientates the metabolism. The endogenous microflora responsible of H2 production from 'solid grape residues' biomass (50 ± 6 L.L-1biomass with a 2.0 ± 0.2 mol.mol-1 yield) through acetate/butyrate pathways belongs to Clostridiaceae family while the one responsible of H2 production from 'grape pomace' biomass (20 ± 4 L.kg-1biomass with a 1.3 ± 0.3 mol.mol-1 yield) through acetate/ethanol pathways belongs to Enterobacteriaceae family.

Abstract (French)

Dans un contexte de transition energetique, ce travail de recherche s'inscrit dans la dynamique d'explorer la potentialite de nouvelles biomasses pour la production d'un vecteur energetique propre, l'hydrogene (H2). Au cours de cette these, un procede de production d'H2 par fermentation endogene et sans depense energetique supplementaire, a ete elabore a partir de biomasses viticoles, et l'influence de parametres operatoires a ete testee. Enfin, le type de biomasses influe sur la production d'H2, non seulement par sa composition biochimique, mais aussi par leur microflore endogene qui oriente le metabolisme. La microflore endogene responsable de la production d'H2 a partir de 'bourbes' (50 ± 6 L/Lbourbes avec un rendement de 2,0 ± 0,2 mol/mol) appartient a la famille Clostridiaceae et est associee aux voies acetate/butyrate, alors que celle des 'marcs' (20 ± 4 L/kgmarcs avec un rendement de 1,3 ± 0,3 mol/mol) appartient aux Enterobacteriaceae et est associee aux voies acetate/ethanol.
